Is Federated HDFS same as having a set of individual Hadoop Clusters, eachmanaging its own namespace and knowing nothing about the existence of otherclusters (but having separate set of data nodes instead of a common pool)?Assuming we have something similar to ViewFS which provides a single globalnamespace combining the namespaces of each namenode and it also providessome facility to add new namenodes to the setup.

What are the differences between Federated HDFS and the above given setup?
